OIL-BURNING' STOCK-TANK HEATER.

Specication of Letters Patent.

Application iilea April as, 1914. serial No. 834,467.

i To all 'whom 'it may concern readily used tank for keeping the latter in a heated condition and which is provided with oil burners and with deflectors so arranged and adjustable with respect to the oil burners as to cause a complete circulation of air in the body of the heater and thereby distribute the heat evenly therethrough.

p The invention consists in the construction, combination and arrangement of devices hereinafter described and claimed.

In the accompanying drawings z-Figure 1 is a perspective view of an oil burning stock tank heater constructed in accordance with my invention. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a vertical transverse sectlonal view of the same in connection with the stock tank. Fig. 4-

is a detail view.

The body 1 of my improved stock tank heater is of oblong rectangular form and is provided on one side at its center with a tubular arm 2 which is inclined and the lower end of which communicates with the body as shown. The top 3 of thev tubular arm is provided with an opening which is normally closedby a lid 4. The lid is provided with a handle 5. The top of the arm is also provided with Van air intake opening 6. A securing bar 7 is arranged longltudinally on the center of the body 1 and is used in connection with screw pins 8 to secure the body ofthe heater on any suitable base or support. A pipe 9 which serves as an outlet for the products of combustion rises from the top of the body at a point near its rear side and in line with its longitudinal center. An oil tank 10 is provided which has an oil feed pipe 11 that is arranged on one side of the tubular arm 2 and enters the body 1. A cross pipe or burner pipe 12 is arranged longitudinally in the `center of the body and vattached to and supported by the pipe 11. Burners 13, for burning oil, are supported by and attached to the pipe 12 and are provided with regulating valves 14: which may be reached through the tubular arm 2 when the cover 4 has been removed.

A detlector 15 is arranged behind each burner and is supported by a forked arm 16 detachably clamped to the pipe 12 in such a manner as to render the arm adjustable about the pipe. Thesedelectors extend upwardly and rearwardly and serve to deflect the heat from the burners forwardly in the upper part of the body and such deflected heat or heated air then strikes the front wall of the body and passes downwardly, then passes rearwardly -over the bottom of the body and then upwardly near the rear wall of the body and finally escapes through the pipe 9,.so that a complete circulation of highly heated air is maintained in the body of the heater by the action of the deflectors and burners, asindicated by the arrows in Fig. 2.

When the burners have been started and adjusted no further attention is required exceptmg to cause the oil tank 10 to be replenished with fuel oil so that the heater can burn continuously, day and night, practically with no attention.

The heater may be made of any suitable size and supplied with any desired number of burners and delectors within the scope of my invention.

While I have herein shown and described a preferred' form of my invention I would have it understood that changes may be made in the form, proportion and construction of the several parts without departing from the spirit of the invention and within the scope of the appended claim.

Having thus described my invention, I claimz- In a tank heater of the class described, a body, spaced inlet and outlet pipes communicating with the interior of said body between the ends thereof, said pipes extending above the body to enable the same to be vided With spaced burners, de ectors dis-- posed between said burners and outlet pipe, and a forked arm carried by each deflector detachably and adjustably connected with the burner pipe.

In testimony whereof I aix my signature in presence of two Witnesses.
